4-Post FreeSpan™ Shelving

Spacesaver Logo
A white 4-Post Freespan™ Shelving system with many adjustable metal shelf levels filled with numerous types of merchandise including hanging shirts, stacked shoeboxes, basketballs, helmets, and books. A partial section of the system on the left is a glass-enclosed display case with a series of lower drawers.

Diverse storage needs demand flexibility. With Spacesaver’s 4-Post FreeSpan™ Shelving, you get exactly that. This clip-type steel shelving system is designed to adapt to your needs with patent-pending clips, adjustable shelves, and a variety of accessories to create the storage space you need. It functions as either a standalone stationary system or can be mounted on a movable system, depending on your needs.

The storage professionals at Hi-Cube Storage Products can custom design a temporary portable shelter or a permanent modular building to suit your specific needs. We offer standard sizes from 32′ and 50′ wide and have built custom structures up to 160′ wide. We can give you all the open space you need. Each portable building is individually engineered and designed to meet all your requirements as well as local building codes.

How the System Works:

Our economical portable building system is composed of an engineered tubular steel framework, covered with a durable, flame retardant fabric. This special vinyl and polyester weave fabric, designed and manufactured in Europe, is conservatively rated for 10 years. Field tests in tropical and arctic temperatures have shown no degradation of the fabric structure’s performance over time.

Our translucent dome roof provides plenty of interior illumination, even on dull overcast days. No foundation is required, though you may choose to use a concrete pad. The only requirement for our building system is level ground.

Benefits:

Versatility:

  • Plain, slotted, or perforated shelving options for your needs.
  • Wide range of accessories to adapt the system to your space.
  • Shelf height adjustability in ¾” increments with the same clip.

Quality:

  • Heavy-duty upright construction.
  • Meets ANSI MH28.1-2024a standards and is tested to a 2x safety factor.
  • Perforated shelves meet NFPA standards and support fire suppression, air flow, and ventilation needs.

Proven Performance:

  • Tool-free for 3x faster shelf adjustment than traditional 4-Post Shelving.
  • Backward-compatible with existing 4-Post Shelving and mobile storage units.
  • Innovative clip design, patent pending, with double-rivet attachment
